This" invention rela tes to machines for spinning textile fibres, such aSTCOttOII or .'wool, and relates more particularly to the means provided for receivin the yarnuor rovingwhen one OIMII'IOIG endsofyarn' are broken.7 f It is the object of my invention to provide cavenger or clearer rollfor a spinning frame so constructed that the roll will be continuously rotated during the normal oper-' ationof the machine, catching and winding;

"up the yarn orrovingonbreakageflof yarn ends. I further provide driving c'onnections for the scavenger roll permitting the roll to yield, and come torest in thefevent that the handsor clothingof theoperator are caught thereby. L 1 i I 17" Myinvention further relates to arrange-j ments and combinations of 7 parts which will be hereinafter described and 7more particularly pointed outfin the: appended claim. 7 A preferred form of the invention is shown in the drawings in which I 7 7 Fig. his a front elevation of parts, of a 2 W001 spinning frame embodyingimy improvements; f

ery of theroll is rather 7 path of the yarn Y as itis drawn downward from the drawing rolls 12 13 to guide i The front drawing roll positively rotating drawing rolls 137 are and j the shaft scavenger rolls 34, spacedto correspond with twisting heads 11 The rolls34 are preferably covered with fabric or other material adapted to easily 7catchfan1d retain a broken end of yarn- 0rroving, and the front portion of b0ard18. 7 e 7 i 7 When a yarnend is broken, the loose yarn or; roving readily engages the adjacent scavenger roll 34 and is wound up thereon, @thuspreventingthe yarn'becoming entangled with adjacent roving and causing breakage of additional yarn ends. h a h 7 The shaft 30 is providedwith a gear 740,

engaged by a pinion 41 on the frontdrawing .-roll or shaft-12. The pinion 41 is positively driven but the gear 4071s yieldi l connected with the shaft 30, these connections being I bestshown inFigsB and 4. 77

The gear 4O is rotatably mounted on the hub portion 42 of a collar 44, securedto the shaft 30 by a headless set screw 45 or in any suitable or convenient manner. 1 A friction tions of the gear 40 and collar the disc 47 against the side surface of the gear 40, and the thrust of the springs 49 is received by a collar 50, mounted on the shaft scavenger rolls 34 are normally continuously Iotatedbythe gear 40 through thefriction driving a connection above described. It somewhat frequently happens, however, that JhshaRsO isprovidedwith a series of i e e the periphclosely adjacent the disc 47 is inserted between adjacentside por- 7 I. a

44, the disc it beingheld from rotation rclativeto the collar 44 by apin or key 48. Springs 49 press the operator, while endeavoring to remove the accumulation of yarn or roving from a scavenger roll, hashis fingers or clothing roll and the brackets 54 by which the rear result if itwere not for the provision of the friction driving connection between the gear This connection adds caught on the roll, or between the supported; When this materially to the safety 'of operation of the machine and substantially reduces the chance I for accident dile to engagementwith thescav enger rolls. r Having thus described my invention and the advantages thereof, 1 do not Wish to be limited to the details herein=c1isc1osec1Other- Wise thanas set forth in theclaims but What Iclaim is1: V In as pmn'i'ng frame, drawing-r011 di-awiw-rg mus "chereojfi;i zrddi titinal flmw'ing rolls engaging therewith, 'ajscavengei' r011 shaft, a scavenger "r011 'fiher'eon below said f v dmwing'1'011s,;and immediately zpdjeceritighe normal pathofyarn frem-the drawing r0118, means tQjjOfifitB said scayenger' roll in afidefic espeed eletien jtc- 'tlie nobaticn 6f Said 7 dra iviiig 1fc1'1s, said ro'ta tin means including an extension oneachei 'fsiaic s'lifafts ajttheside u offiherespective rollsfa'nd geiufingfconlnec'ting I said ezit'ens'icfis, said jgegilrii igfihcl'uding a FRED ,K- HENDRIQKSOQ iii) f (in
